SAUGERTIES — Police say a 57-year-old Montgomery man suffered arm and back injuries Friday when he was hit by a 43-foot tractor-trailer while directing truck traffic.

Saugerties police say Keith Muller was directing two tractor-trailers at the corner of Main Street and Washington Avenue in the village when he ended up getting struck by one of them.

According to police, Muller said he had waved one tractor-trailer through the intersection, and believing it had completely passed his location, he began to walk backward on Main Street as he started to wave the tractor trailer on from Washington Avenue. But police said the first tractor-trailer had not completely passed, Muller’s arm got caught and he was flipped around into the trailer portion of the passing truck.

Witnesses said Muller was wearing a safety vest and helmet when he was struck.
